ted or broken awa to more clearly illustrate Be it known that I, ALEXANDER T. BROWN,

other features of t c machine.

I have illustrated myinvention applied toY a front-strike type-writing machine, though it should be understood that the various features of the invention may be embodied in i other characters of writing-machines.

The frame of the machine comprises a base 1, surmounted by a frame or casting l2, which and fixed parts of the machine as will hereinafter more clearl appear. the upper side o the base l'are arms or rods 3, which, together with a supporting-plate 4,

constitute su ports for a platform 5, that is provided wit upwardly-projecting bearinge recep ion o piv- 10 and has its opposite end connected at 11 supports the carriage .and yarious working Y Depending from 'I to a draw-linkv 12, the opposite end of which is connected at 13 to a projection that extends from a type-bar 14. The type-bars 14 v are supported upon hangers 15, which are secured to a segmentl 16, supported upon the casting or frame 2. Extending forwardly from the segment are arms 17, tov the outer ends of which a segmental support 18 is secured to su type-bars. lever extends into the path of a segmental universal bar 19, connected at or near its endsfto upright arms 20, that are pivotedfat 21 to the forwardly-'projecting brackets 17. Each of the` arms 201s connected at 22 to a rearort the forward ends ofthe he upright arm 9 of each keywardly-extended link 23, the rear endV of which is connected at 24 lto'a'depending crank-arm 25, extending from a rock-shaft' 26,. mounted in the frame 2 and extending from side to side of the machine. This rockshaft and the parts carried thereby are re` stored to the. normal position by a coiled spring 27, vthat surrounds the shaft and is connected'at one end 28 to a portion of the ixed'frame 2 and at its opposite en'd to one of the depending crank-arms 25, whereas a spring 9", connected through a link 9" to each key-lever, restores it and the associated typebar to the normal position when pressure on the l finger-key is released. The rock-shaft 26 carries two rigid feed-dogs 29, which coperate with an escapement-wheel 30 to aflord a step- '1y-step feed movement of the carriage. he escapement-wheel 30 is rigidly secured to a shaft 31, (seeifig. 2,) that is mounted in bearings 1n the frame 2 and has IIO a looselymounted surrounding slreevem/Y32, which is provided with a' pinion 33; The rear end of the sleeve 32 is formed as one member of a two-part clutch, the other member of which is formed by alike sleeve 34, that surrounds the shaft and rigidly secured thereto by a pin 35. Asshown'inFig.

' 9, the sleeve 32 is provided with a recess or fork or yoke40 straddles the sleeve 32 and bears against one side of the pinion 33. The body portion orcarrier 41 of the fork is of general U shape and is perforated for the re. ception of a fixed pin 42 and a contracted ex tension 43 at the end thereof and' pn which the yoke is adapted to slide. The shoulder 44, formed at the junction of the contracted portion 43-and the pin, constitutes an abutment which limits the movement of the yoke toward the rear of the machine, and a coiledspring 45 surrounds the pin 42 and is connected at one end thereto, and theo posite epd bears upon one of the ends of the fiody of the yoke and tends vto force the yoke toward the rear of the machine. The body'of the yoke is provided with a laterally-projecting pin 46, which is received within an elongated s lot 47 (see Flg. 1) in a lever 48, which is pivoted at 49 and carries a bar 50 at its upper end, that extends transversely from side to side of the machine, the opposite end of said bar being provided with a ink or arm pivoted to the frame of the machine in a similar man ner to the lever 48'. A rock-bar 51 is carried by the carriage and has a finger-piece 52, by means of which lit may be turned on its pivots 53. See 2.) The' rock-bar has a depending finger 54 adapted -to coperate with the cross-bar irrespective of the position of the carriage or at any point in the movement thereof from side to side of the .ehina When the finger-piece 52 is moved toward the front of the machine, the dependmg fngervwill be moved rearwardly, thus moving the bar 50 in a like direction and forcing the ryoke 40 toward lthe front of the machine., he effect of this @movement is to move the sleeve 32 and'itspinjonfforwardly, thereby disconnecting the iclutchsections without moving the pinion ont of mesh withits companion gear. The effectof this disconnectlon of the clutch-sections is toentlrely release the carriage from Vthe escapement mechanism, as will hereinafter more clearly appear. When thecarriage is grasped at an suitable portion thereof. and moved from eft to right without moving the releasekey 52, the clutch-section 32 will be cammed 'of the section 34, while the escapement-wheel -will remain at rest, being engaged by .oneof v 2the feed-dogs.

`riage is a feed-rack lframe 2 of the machine.-

is provided with a beveled pinion 63,- that y,meshes with a companion bevelpinion 64 on a shaft 65, supported in suitablel bearings in larrives at its highest -point when a complete out of engagement with its companion teeth of the section 32 will jog over-the teeth The carriage comprises cross-:bars 55, y which have tracks or grooves 56" therein for 7 the reception of antifriction rollers/or'balls 57, that are likewise received in co'm anion raceways or tracks 58, securedy to the ame 2 of the machine. Extending upwardly and uniting the cross-bars 55 are end plates`59 andn 5.9, which constitute supports for vari# ous portions of the carriage structure. .S'ecuredto one of the cross-bars 55 of the'vcarwhich is in constant mesh with a gear-Wheel 61, ri idly connected to a shaft 62, supported .in

earmgs inthe This gear-wheel 61 the frame 2. The opposite end of the shaft 65 is provided with a gear-wheel 66, with which a toothed segment .'67 meshes. This toothed segment is pivoted. at 68 to av for.- ward-ly-extending bracket 69 and is extended at 70 toforrn a handle by means of which the segment and the arts controlled thereby may be moved. T e segment has astrap1 or band 71 secured thereto at 72 and whicA is adapted to bear upon a segmental ortion 73, formed on the body portlon of t e-toothed segment. The opposite end of this strap is connected to a contractile spring 74, which is connected at its opposite end 75 to a strap 76, that has its opposite end secured by a screw 77 to a-bloc 78, tapped and received on the threaded rod 79, which is loosely supported at its rear end in a fixed bearing 80V and at its forward endin the -base 1 of the machine, the forward end bein provided with a nicked head 81, whereby t e rod may be turnedl to eHect an adjustment of the block 78 to vary the tension on the sprin 74.

From the foregoing description it wil be understood that'the spring 74 constitutes a carriage-spring which exerts pressure on the toothed segment 67, fthelf; companion fgearwheel 66, the bevelj-jg'ears',4 64 and 63, and through the gear-wheel 61 to `the. racklon the 1 A carriage and tends to move the carriage from-1A right to left. 2 During t his movement' of the Acarriage from right to left the lhand-lever 70 will receive an upward movement', so that it movement of the carriage has taken place. Itwill likewise be understood that a depression of the lever 70` will cause the toothed segment 67 to be moved in the direction of l the arrow adjacent thereto, thereby turning the various gears an opposite direction -IZO . riage from left toright in order to restore it to its initial positionto begin a new line of Wrlting, and the spring 74 is at the same time stretched to increase its tension. During the actuation of the machine a de ression of an of the finger-keys will causet e correspon ing upright arm 9 of the lever to vibrate the segmental universal bar 19,'thus moving the feed-dogs 29 toward the front of the machine. When the fnger-keyis released,.the feed-dogs will be moved toward the rear of the m'achine by their spring and a letterspace feed movement of the escapementwheel 30 will be effected. The pressure exerted by the sprin 74 will tend to move the various gears in t e manner heretofore described to move the carriage a letter-space distance when the es capement mechanism has been actuated in the manner described.

The platen 82 is adapted to rotate in its platen-frame 83, through which the shaft 84 of the fpllaten extends, the platen-shaft havingl a ger-Wheel 85 secured to each end thereof by a screw. 86 and by means of which the platen may be turned in either direction.

The platenshaft and frame are supported at one end by a suitable link that is pivoted to the end plate 59. The shaft 4and platenframe are supported near its opposite end by a .link 87, which is shown in detail in Fig. 10 and which is pivoted upon a headed screwpivot 88, that extends throughthe end plate 59a of the carriage (see Fig. 6a) and through the link. The link 87 is provided with a ,flange 89, that projects laterallytherefrom around its entire edge and conforms at varions portions thereof to the general contour of the gears, which'are contained within the flange. Thus the gear 90 is received within l the flange at that portion indicated at 90,

Whereas the gear 91 is received'within that portion of the flange indicated at 91, vand the gear 92 is received within that portion of' the flange indicated at 92a. These' three ears 90, 91, and 92 are in mesh, the gear 91 ein in the nature of an idler or intermediate whic is carried b a headed intle 93, that. projects laterally therefore be seen that the link 87 not only constitutes a'link, but likewise forms by its flange a protective housing for the various gears. A ratchet-wheel 94 is located adjacent to the gear-wheel 92 vand is secured to rotate therewith by pins 95, which ,extendA through the ratchet-wheel and gear.A The gear-wheel is rigidly connected toa collar 96,.formed on the platen-head 97, las indicated in'Fig. 11, whereas peripheral teeth 98 are formed on the head, so as to constitute a line-spacing detent-Wheelwith which a devtent-:98a c o" crates', the platen-head itself the tension of the om the 87. VIt

screws 99, andthe platen-shaft 8d4 may be se- Ycured to the platen by. any suitable-'means.

Thus it will 'be understood that motion transmitted from the gear 92 throu h rthe idler or intermediate 91 and gear 90 w' l effect a linespacing movement o theplaten; f

A sleeve 100 is loosely seated upon th'e fixed pintle 88 and 'is extended outwardly to form a bearing for the wheels 9 2 and94, and

the sleeve is prevented from being removed from the -pintle bythe head,of ja se arate' screw 88, the stem ofwhich is/ receive within a threaded openin in the end of the pintle 88, Fig. whereas t e pintle itself is held in place on the end plate 59 of the carriage opening in the end plate.

bifurcated at its lower en as indicated at 101, and has a pivot-pin 102. extendin through the bifurcated portion, and the hea `which is received within the bifurcation and has, a de ending arm 105 rounded at its the pi-votextends beyond the. outer' lower en for coperation with the forked of the bifurcated portion of the arm 101, and

Athus limit the movementof the paw] in one direction, as represented -in Fig. 4. 'A spring 'is lconnected at one end to the cross-bar' 109 and bears at its free end against the IOO pawl in order to assist in throwing the engaging nose thereof out of engagement with the teeth of the ratchet-wheel 94. A frictionspring 111 is perforated at one end in order that it may be seated on the screw-pivot 102 between the head 103 thereof and one side of the bifurcated portion 101a of the arm 101.

This friction-sprin is bentlaterally, as in dicatedin Fig. 3, an 'the free end thereof bears.

at all times a ainst the inner side of the end plate`.59 of t e carriage.' The tension and frietional contact of the spring 111 exceeds s rin 110, so that a movement of the right-lian end of-the lever 107 IIO IIb

toward-theA front of themachine'is effective to force the pawl104into en agement with theteeth of the ratchet-Whee 94 before any movement isy transmitted to the arm 101.

-Thelever 107 is ivoted at 1`12 to one of .the cross-bars 55'of t e carriage and is provided' with a-la'terally-exten'ding' lug 11 3, to jwhich one -end of a contractile sprin connected at 1 15 to a-fixed portion of t ecarriage; so 4that the\tension of the sprin 114 normally tends to force the lever in a ection opposite to that indicated by the arrow in Fig. 2.

AThe opposite end of the lever from that I 114 isconnected, the opposite end of sai sprin lbei'ng the lever 107,/to limit the movement of the pawl in one direction relative to the lever.

he lever/107 has a spring 120 secured thereto at .121, the opposite end offsaid spring bearing against a shoulder 122 on the pawl,

io so that the tension of the spring '120 is ex- Y erted on the pawl and tends to maintain the lug 118, in contact with the shoulder 119 on lthe lever. The free endof this -socalled controlling-pawl vis provided with a teat i 5 123, which is rounded and conforms generallyv to the spaces or serrations 124 in a rack 125, secured by screws 126 to one ofthe rails or tracks 58, secured tothe lframe 2 of the may chine. The Jree end ofthe awl is likewise zc. provided with a smooth-face shoe 127, that is adjacent to the teat 123, and therelation of the parts is such that the shoe is maintained out of contact with the rack when the .pawl is in' the position indicated in Fig. 2 and main- 2 5 `tains this position throughout the move-l 5 ment-'of the carriage in the direction of its feed, or from right to left, the teat on the pawl at this time jogging over the teeth of the rack V125 and the ine-spacing pa-wl 104 being 3o maintained out of engagement with its cooperatingline-spaee ratchet-wheel 94. The p aten at thisv time will be maintained inthev ositionl to which it has been moved by the etent 98 bearing on the wheel 98. As soon 3'5 as the c'arria'e starts to move in an opposite direction, or llronileft to right, in order to begin a near line .of writing the free end of the pawl 116 will be maintained iixed bv the rack throughout the initial portion of this move- 4d ment, Whereas the carriage, with its lever 107,

will be moved to the right, so that the rela- `tive disposition between the pawl 116 and the lever 107 will be changed. Thus while the carriage is being moved from right to left .i5 the pawl 116 is at an acutc angle to the lever 107. When, however, the carriage moves from left to right, the free end of the pawl 4will be rocked on and maintained in engagement with its rack 125 and the lever 107 will 5o -continue to move with the carriage, thereby graduali increasing the acute angle -between the paw 116 and its lever 107 until the lug 118 is arrested by contact with the shoulder.

119, at which time the pawl and lever are at 5 5 substantially ri ht ang es one to the other,

and the pawl wi lV then move bodily with the lever and carriage. During this relative movement of the pawl to the lever a movement of the lever around its pivot 11 2 has 6o been effected, and this movement is effective to first turn the line-spacin ratchet-pawl 104A on its pivot 102 against t e tension of the spring 110 from the osition shown in Fig. 4 to that indicated in ig. 5 in` order to bring the nose of the pawl into contact with the vriage U Avan expanslon-s'pring 134, oneend of said teeth of the line spacing ratchet wheel. After such engagement has been attained a f further relative movement between the linespacin ratchet-pawl and the arm 101 cancarriage, with which it is maintained in conv tact. When the pa'wl 116l has attained itsn position at right angles to the lever 107, the teat v123 will be movedl out` of effective or meshing en agement with the teeth of the ,rack 125 van the flat face of the shoe 127 will be brought into alinement with the flat crowns 128 of the teeth on the rack and the pawl will be permitted' to slide `along the teeth with the carriage to maintain the arts vin the positions towhich they have een moved. soon, however, as the carriage starts to move` in an opposite direction, lor from right to left, the controlling-pawl will'be rocked against the tension'of its spring 120A l and the teat 123 on the pawl will be seated in a serration 124l so as to be engaged by the teeth formed thereby, and the pawl will be rocked around its pivot 1 17. The disposition of the pawl relative to the lever being thus changed to an acute an le, the tension of the spring 114 will move t e right-hand end 'of the lever 107 toward the rear of the machine.` The `first effect of this movement is toimmediately throw the nose of the pawl104 out of engagement with the teeth of theratchetwhee 94, the sprin assisting in this movement. When t is initial movement of the pawl out of engagement with the lteeth has been effected, the lug or stop1108 on the pawl is brought into engagement withthe crossbar 109 on the carrier 101, and the carrier 101 and pawl are then moved together back to the initial position where the pawl is in a position to engage the desired toothon the ratchetwhee `to effect the proper line-spacing movement when the carriage is again moved to the right. In order that this extent of linespacing movement may be varied, I have provided a regulating device which is shown in detail in Figs. 7,8, and -9 and which cfonsists oi: a plate 129, thatghas an elongated openin 130 therein for the reception of thev stem o a headed screw 131, the stem of the screw taking in a threaded opening in the rear IIO edge of the end plate 593L of the carria e. By

these means a vertical movement of t e regulating-plate 12'9 may be effected, and a handle or finger-piece 132 1s provided on the plate in order to ao'rd a movment thereof to the desiredposition. The end plate 59a of the caras a recess 133 therein, which contains recess and the opposite end of the s ring i -bearing against alocking-ball 136, whlch is spring bearing against an end wall 135 of the received and travels in. the recess and maybe seated -*in any one of three depressions 137 in one face of the controlling-plate 129 in order that the plate may be maintained in any one bear upon opposite sides of the end late 59"V of the carriage in order to guide t e late.

The inner edge or side 138 of this contro lingpiece is provided with three faces, steps, or

abutments 139, 140, and 141, respectively,

with which the head 103 of the screw-pivot 102' is adapted to abut, as indicated in dotted lines in Fig. 8, thus limiting the swinging movement of the arm 101 toward the rear of the machine around its pivotal center. Thus if the controlling-piece 129 is adjusted so that the abutment 139 thereouis brought into the path of the head 103 of the pivot the abutment will provide. the shortest extent of throw to the carrier or arm 101, s o that the extent 'of line-spacing movement will be accordingly lessened ,.whereas if the controllinglate is moved to bring the abutment 141 into the path` of the head 103 of the screwployed for shifting the platen for upper and lower ease printing, that shown in the present instance consists of a rock-'shaft 143, that extends from side to sidevof the machine and is supported in suitable hearings in the frame 2. This rock-shaft is provided with a crankarm 144, to which the upper end of the link 145 is pivoted at 146, the lower end of said ating-lever 148, that may be provided with a key (not shown) which extends to the keyboard of the machine. The rock-shaft 143 has a plate 149, that extends throughout the length thereof and is rigidly secured to or formedk integral with the rock-shaft. An antifriction-roller 150 'is pivoted to a depending arm 151, that extends from' arock-shaft 152, mounted to rock in hearings 153, which projectforwardly from one of tie cross-bars '55 ofthe carriage. This rock-shaft is prof yvided withforwardly and upwardly projecting arms 154, one at each end thereof, the forward ends of these arms being pivoted to the platen-frame 83. Adepression of the finger-key connected to the lever 148 will cause the link 45 to he elevated, thereby rocking the shaft 143, and the effect 'of this movement is to vibrate the rock-shaft 152 on the carriage, thus shifting the. platen-frame and platen on the links, one of which consists of the link 87,- around the pivotal center 88, thereby moving the platen from the lowermostposition to the u lper position, wliere it ma coperate with t e types on the outerl en s of the type-hars. When the shift-key iis released, the platen and the parts connectpivot the longest extent of throw of the arm'ed thereto are restored to normal positions 101 is provided and the line-spacing movement 'of t e platen is therefore afforded.

In order that the carriage may be moved from left.to right without line-spacing when desired, I have provided the rock-bar 51 with an upwardly-extending curved finger 142, which projects in the path of movement of the carrier 101, so that when the release-key 52 isactuated to release the carriage it will cause the finger 142 to move the arm or carrier 101 forwardly, or to the left in Fig. 6, and thereby effect a slight rocking of the pawl 104 around its pivot-pin 102, so as to move and maintain it out of enfragement with the line-spacing ratchet-whee ,p and when an automatic actuation of the controlling-pawl 1 16 and lever107 takes place during the movement of the carriage from left to right it will be ineffective to turn the platen by reason of the fact that the pawl 104 is maintained out of engagement W1th its cooperating ratchetwheel 94. It will thus be seen that an automatic line-spacing of the platen may or may not be effected during the return of the carriage from left to right in accordance With the desire of the o erator.

While any suita le mechanism may he emreatest extent of4 ried by a fixed portion of the machine, whereas other portions of the line-spacing mec-hanmovement of the carriage to the rightvathd that the automatic line-spacing is effected in` turn the carriage to theright'. sary, therefore, to move the carriage to its 'extreme right-hand position in order to effect an automatic line-spacing.

The fact that the actuation ofV the linespacing mechanism is entirely 'independent of the means employed for restoring the carriage to the right enables me to use any suit-A able means for this purpose, and from certain p aspectsof my invention it is immaterial what ing the carriage to the right, whether it be the ordinary hand-lever or any other suitable link being pivoted at 147 to a suitable actue IOO line-spacing mechanism (the rack 125) is car- L IIO ism are carried by the carriage and coperatie with the relatively fixed portion or rack to l automatically actuate the line-spacing mech-1,l anism during the initial portion of the'returii dependently of the ymeans employed to re` t It is unnecescharacter of means are employed for returnmeans, or the carriage may be grasped by any suitable portion thereof and pushed to the right, and yet the automatic line-spacing will be effected.

The structure is such that the intermeshing gears 90, 91, and 92 are in constant mesh and are connected to the platen and platenframe and likewise to the carriage. It will also be seen that the gear 92 turns on a pivotal center coincident with the .center on which the platen is vibrated to change the case position thereof, so that this movement of the platen may takeplace without in any Way effecting the meshing'` engagement or connection between the various gears. It will also be understood that the gears and 91 vibrate bodily with the link 87 and platen around the pivotal center on which the platen is movedduring the shifting thereof to change the case position ,of the platen-in other Words, that the platen swings on links and is shiftable transversely of its length and relatively to the carriage to change the case position ,of the platen. Furthermore, a linespacing wheel 94 and a gear 92 are carried by the carriage and turn on the center on which the links swing, and movement is transmitted from the line-spacing wheel and gear 92 on the carriage to the platen through means or. gear connections carried by `one of said links.

The line-spacing pawl being normally out of engagement with its coperating line-spac- Ving ratchet-Wheel, either of the finger-wheels may at any time be employed to rotate the platen in either direction, and the platen will be retained in the position to which it may be moved by the detent 98a and its cooperating detent-wheel.

Various changes may be made without departing fromthe spirit of my invention and certain features may be employed without the others'.
